Title: Manufacture of stretched film and device thereof
Inventor: ARAI TOSHISHIGE
IPC: B29C48/90
Filed: 1985-03-04
Abstract: PURPOSE:To prevent film from being stained due to the contamination of the surface of a mandrel and elongate the intervals of interruption for cleaning the mandrel by a structure wherein the mandrel is shifted so that the molten resin extruded from a die contacts with the clean portion of the mandrel at all times. CONSTITUTION:Molten resin 11 is, at first, extruded from a nozzle 10 under the state that the gap between a mandrel 2 and a die 1 is kept at the maximum gap by screwing bolts 9 in to their limits. The resin moves upwards along the outside of the mandrel 2 so as to form stalk 3. Because the heat decomposition product of the molten resin adheres onto the surface of the lower end 12 of the mandrel so as to accumulate, the area, onto which the decomposition product adheres, is moved downwards in order to form the stock onto the clean surface of the mandrel by lowering rods 8 with the screwing-out of the bolts 9. The mixing of the heat decomposition product with the stalk is avoided by contacting the clean surface of the mandrel with the stock at all times with the lowering of the mandrel.

Title: Circuit preventing decrease in quantity of echo cancellation in duplex call by echo canceler
Inventor: HASEGAWA ATSUSHI
IPC: H04B3/20
Filed: 1992-02-28
Abstract: PURPOSE:To prevent the quantity of echo cancellation in a duplex call state from decreasing and make the disorder of estimation in the call small by decreasing an residue epsilon used for estimation arithmetic when a transmitted input signal Sin is large. CONSTITUTION:When a level deciding circuit 50 judges that a received input signal Rin is lower than the specific level, a switching circuit 30 forcibly set the signal epsilon to 0. Then when a reception-side speaker signal RT is absent and a received output signal Rout is present, the transmitted input signal Sin becomes an echo and an echo path estimation state is entered. In this state, estimating operation is advanced to eliminates the echo. When the RT becomes large in this state and a duplex call is started, the amplitude of the Sin becomes large and the output of a signal varying circuit 40 becomes small. Consequently, the signal epsilon inputted to the echo canceler 10 becomes small to prevent the estimating operation from being disordered. Consequently, the disorder of the estimating operation in the duplex call state is made small to prevent the quantity of echo cancellation from decreasing.

Title: Direct type heat exchanger
Inventor: AKATSU YASUAKI
IPC: F28C3/06
Filed: 1978-04-14
Abstract: PURPOSE: To improve heat exchangeability by providing a partitioning plate in the direction of dividing flow in a heat exchanger so as to prevent joining of low boiling point media's steaming foams.  
     CONSTITUTION: Heating side's heating media introduced from a heating media intake passes through a low boiling point media branch pipe 2, undergoes heat exchange in a space formed by a partitioning plate 4 and becomes discharged from a hot media outlet. Heated side's low boiling point media is jetted out from jetting branch pipe's jet hole 3 toward a space formed by the partitioning plate. Thus jetted out low boiling point media exchanges heat with the heating media and becomes turned into steaming foams 5 after undergoing phasic change from a fluid body to a gaseous body. The steaming foams 5 go up while joining with each other in the space, leave the liquid surface and become discharged. By providing such a partitioning plate 4, joining of the steaming foams 5 become limited in joining area and size, and the foams become uniformly distributed in a heat exchanger, and therefore, occurrences of whirlpool and partial flow are prevented and heat exchangability is improved.
